“…Half of the specimens (1a–8a) were then stored in distilled water at 37°C for 24 hours for immediate testing. The remaining half samples from each group (1b–8b) were stored in artificial saliva (ICPA, Wet Mouth) for 6 months before shear bond strength evaluation [ 30 , 31 ]. Shear bond strength was determined using a universal testing machine (Instron, ADMET, Enkay Enterprises, New Delhi) using the corresponding computer software.…”

Objective. This study evaluated the effect of ethylenediaminetetraacetic acid (EDTA) conditioning and carbodiimide (EDC) pretreatment on the shear bond strength of two all-in-one self-etch adhesives to dentin. Methods. Flat coronal dentin surfaces were prepared on one hundred and sixty extracted human molars. Teeth were randomly divided into eight groups according to two different self-etch adhesives used [G-Bond and OptiBond-All-In-One] and four different surface pretreatments: (a) adhesive applied following manufacturer's instructions; (b) dentin conditioning with 24% EDTA gel prior to application of adhesive; (c) EDC pretreatment followed by application of adhesive; (d) application of EDC on EDTA conditioned dentin surface followed by application of adhesive. Composite restorations were placed in all the samples. Ten samples from each group were subjected to immediate and delayed (6-month storage in artificial saliva) shear bond strength evaluation. Data collected was subjected to statistical analysis using three-way ANOVA and post hoc Tukey's test at a significance level of p < 0.05. Results and Conclusion. EDTA preconditioning as well as EDC pretreatment alone had no significant effect on the immediate and delayed bond strengths of either of the adhesives. However, EDC pretreatment on EDTA conditioned dentin surface resulted in preservation of resin-dentin bond strength of both adhesives with no significant fall over six months.

“…However, sealant placement during this period is challenging because the contact of the tooth with the distal marginal ridge of the gingiva facilitates the contamination of the occlusal surface by moisture or saliva (6), which is the most common cause of sealant failure (2). The microspores produced by acid etching may be partially occluded after a contamination time as short as one second (7).…”

Dental sealants are important for prevention of carious lesions, if they have good shear strength. The aim of this study was to evaluate the shear bond strength (SBS) of two sealants to saliva-contaminated and non-contaminated enamel with and without an intermediate adhesive layer underneath the sealant. Ninety flat enamel surfaces from human third molars were randomly assigned to 6 groups (n=15): F (control): Fluroshield™ sealant; EWB (control): Embrace™ WetBond™; SB/F: Single Bond adhesive system + F; SB/ EWB, s-SB/F and s-SB/EWB. In the s-SB/F and s-SB/EWB groups, the acid-etched enamel was contaminated with 0.01 mL of fresh human saliva for 20 s. Sealant cylinders were bonded to enamel surface with and without an intermediate adhesive system layer. The shear tests were performed using a universal testing machine (0.5 mm/min). Data were analyzed statistically by Kruskal-Wallis and Mann-Whitney tests (α=0.05). F presented higher mean SBS than EWB in all experimental conditions. The lowest SBS mean was obtained for EWB on contaminated enamel (p<0.05). In conclusion, an adhesive system layer should be used prior to sealant placement, in both dry and saliva-contaminated enamel. F had the best performance in all experimental conditions. EWB sealant showed very low results, but an adhesive layer underneath the sealant increased its SBS even after salivary contamination.

“…Los selladores Clinpro® evaluados en los dos tipos de ambientes (seco y húmedo) se comportaron casi iguales, no hubo diferencia significativa en la formación de tags (92-82% respectivamente según la clasificación de Celiberti y Lussi) Grafica 1, figura 3; Sin embargo el grupo 7 y 8 (UltraSeal XT Plus®) en ambiente húmedo vs seco, el grupo en ambiente húmedo mostró los peores resultados debido a la contaminación por agua simulando saliva, estos datos corroboran los realizados por Panigrahi et al (2015) en el que concluyen que la saliva o contaminación con humedad afecta la micorfiltración y la adhesión. 23 El sellador Embrace WetBond® obtuvo buenos resultados cuando la superficie del esmalte estaba en condiciones de humedad, estos resultados están en concordancia con los obtenidos en el estudio de Panigrahi et al (2015), en el que encontraron que Embrace Wetbond® podía adherirse en presencia de humedad sin afectar la microfiltración. 23 En los resultados mostrados por UltraSeal Xt Hydro®, también se encontraron mejores resultados en un ambiente húmedo que en seco, basándose en una mejor penetración y adaptabilidad debido a que son hidrófilos.…”

Objetivo: Evaluar el efecto de diferentes marcas de selladores de fosas y fisuras hidrófobos e hidrófilos en Microscopio electrónico de barrido de emisión de campo (MEB-EC) expuestos a humedad relativa. Materiales y Métodos: Se utilizaron 40 premolares extraídos con fines ortodóncicos, se dividieron al azar en 8 grupos: Grupo 1: sellador Clinpro® (ambiente seco), Grupo 2: sellador Clinpro® (ambiente húmedo), Grupo 3: sellador Embrace WetBond® (ambiente seco), Grupo 4: sellador Embrace Wet-Bond® (ambiente húmedo), Grupo 5: sellador UltraSeal XT Hydro® (ambiente seco), Grupo 6: sellador UltraSeal XT Hydro® (ambiente húmedo), Grupo 7: sellador UltraSeal XT Plus® (ambiente seco) y el Grupo 8 sellador UltraSeal XT Plus® (ambiente húmedo). Resultados: El Grupo 1 (Clinpro®/ambiente seco) Mostró valores de adhesión al esmalte superiores, de forma estadísticamente significativa, en relación a los demás grupos y mejor calidad en la formación de “tags” en comparación con los otros grupos, independientemente si el ambiente era seco o húmedo. Conclusiones: Los selladores Clinpro 3M®, utilizados en condiciones secas o de relativa humedad demostró tener buenos resultados. La resina fluida UltraSeal XT Plus® utilizada en condiciones húmedas no proporcionó buenos resultados observándose poca formación de tags; los selladores hidrófilos (Embrace Wetbond ® y UltraSeal XT Hydro®) utilizados en un ambiente húmedo tenían una capacidad de adaptación, observándose buena formación de tags; Los selladores hidrófilos usados en ambientes secos no se adaptan a la superficie y tienen una tendencia a fallar en lo que respecta a la adhesión.
